• Watthour (3,600 J)

  The watt hour (symbol Wh) is a unit of energy equal to 3.6 kilojoules. If energy is transmitted or used at a constant rate (power) over a period of time, the total energy in watt hours is equal to the power in watts multiplied by the time in hours. The kilowatt hour is commonly used as a billing unit for energy delivered to consumers by electric utilities.

• Electronvolt (0.00000000000000000016 J)

  In physics, the electronvolt (symbol eV, also written electron-volt and electron volt) is a unit of energy equal to approximately 1.6×10−19 joules (symbol J) in SI units. By definition, it is the amount of energy gained (or lost) by the charge of a single electron moving across an electric potential difference of one volt. Hence, it has a value of one volt, 1 J/C, multiplied by the electron's elementary charge e, 1.6021766208(98)×10−19 C. Therefore, one electronvolt is equal to 1.6021766208(98)×10−19 J. The electronvolt is not a SI unit, and its definition is empirical (unlike the litre, the light-year and other such non-SI units), where its value in SI units must be obtained experimentally.
